Agenda Introduction Rise of OpenStack OpenStack Details and Ecosystem OpenStack and Xen Cloud Platform - Demo Conclusion 2
Introduction - Simple Cloud Stack 3
Rise of OpenStack IaaS Enabler Cloud Services have three main flavors: IaaS PaaS SaaS For early cloud platforms, IaaS enablement was the key focus Help organizations build their own public, private, or hybrid clouds 4
IaaS Enablement Platforms AKA Cloud Management Platforms, Cloud Controllers, Fabric Managers, Cloud Orchestration, IaaS Platforms, etc Enablement Platforms turn Physical and Virtual IT assets into elastic cloud entities Resulting IaaS can provision and manage Compute, Storage, Networking or other resources in some combination 5
OpenStack Precursor Eucalyptus Eucalyptus was very popular IaaS Platform, grew out of project at UCSB 25,000 installs and big user community NASA used to be one of the big vocal supporters of Eucalyptus In May 2010, NASA partnered with Rackspace to announce a competing effort! 6
Eucalyptus Falters NASA had two main issues with Eucalyptus Scalability of Eucalyptus was insufficient - Nebula project needed massive scalability 1 million machines & 60 million VMs Open Core Vs Open Source NASA engineers were unable to contribute code to some Eucalyptus Modules due to some parts being closed source 7
Nebula Project at NASA 8
Birth of OpenStack: Rackspace+NASA OpenStack Rackspace+NASA collaboration Rackspace Ozone cloud controller and NASA Nova cloud fabric on Nebula Rackspace Cloud Files storage engine 9
Rackspace Motivations Needed something to counter Amazon s rapid pace of innovation Shift to open source builds rapid developer mindshare Focus on their Strengths Customer Support Heterogeneity Support offerings as new revenue stream 10
OpenStack Partners 11
OpenStack Project Objectives Mission: Create an ubiquitous open source cloud computing platform that is simple to implement and massively scalable Open - All code is Apache 2 licensed Simple - Architecture is Modular Scalable Massive scale Design Goals: 1 Million Physical machines, 60 Million VMs Billions of Objects stored 12
OpenStack Flavors OpenStack Compute (Nova) service to Provision and Manage millions of VMs (comparable to Amazon EC2) OpenStack Storage (Swift) service to large-scale, redundant storage of Static Objects (comparable to Amazon S3) OpenStack Image Service (Glance) service to discover and register virtual disk images for use with Nova 13
OpenStack Release Train Three quick releases in under a year Next release Diablo expected in Q3 2011 Diablo focus - Make OpenStack ready for large-scale deployments 14
Architecture of OpenStack 15
Architecture of OpenStack Built on a shared-nothing, messaging-based architecture using AMPQ based queues nova-api process is the heart of the OpenStack Nova its Cloud Controller Provides an endpoint for all API queries Initiates most of the orchestration activities Enforces some policy - mostly quota checks nova-schedule decides which compute host a given VM should be created on 16
OpenStack Architecture Cont d Three Primary Infrastructure Modules nova-compute process primarily creates and terminates virtual machine instances. nova-volume manages the creation, attach & detach of persistent volumes to VMs nova-network manipulate the network e.g. configure VLANs, change iptables rules, etc SQL DB stores run time state of cloud infrastructure such as Instances in use, Networks available, Volumes attached, etc 17
OpenStack Component Specifics Written almost entirely in Python Available pre-built on Ubuntu and RHEL RabbitMQ is the AMPQ product of choice Supports MySQL and PostgreSQL Libvirt, Xen API used in instance creation Support for EC2 API and S3 semantics Supports wide variety of Hypervisors 18
OpenStack Hypervisor Support Hypervisor agnostic support for: Hyper-V 2008 KVM - Kernel-based Virtual Machine QEMU User Mode Linux VMWare - ESX/ESXi 4.1 update 1 Xen - XenServer 5.5 Supports OVF (open virtualization format) 19
Competitors and Implementers Eucalyptus Still very popular OpenNebula Used at FermiLabs, CERN CloudStack Cloud.com s IaaS platform CloudForms Red Hat s IaaS offering (beta) OpenStack in the commercial space: Ubuntu Enterprise Cloud (UEC) Switched from Eucalyptus to OpenStack as base Project Oylumpus Citrix branded OpenStack Internap Rackspace competitor switching 20
OpenStack Ecosystem 21
OpenStack Partners Ecosystem Gaps in Stack filled in by Partners: Billing - Chargeback and Showback Integrated Metering, Capacity Planning Full-Spectrum Monitoring, Analytics Advanced Networking Capabilities Management Systems Cisco has come out with a Networking as a Service (NaaS) Proposal for OpenStack Zenoss and CloudKick for monitoring 22
Ecosystem-Facebook OpenCompute Facebook recently open sourced their proprietary datacenter designs under OpenCompute project Puts all the secret sauce of their datacenter and sever design on the web Collaborating with OpenStack to ensure seamless deployment on Open Compute Power savings of 38%, cost savings 24% 23
Ecosystem Xen Cloud Platform Xen Cloud Platform Open source platform to build clouds Virtualization platform including Xen hypervisor Network and Storage support Originally derived from XenServer GPL2 24
XCP Architecture 25
OpenStack and XCP OpenStack is hypervisor independent Designed to work with XenServer & XCP Xen Cloud Platform (XCP) is the cloud optimized and Open source version of Xen OpenStack plays the role of cloud orchestration platform XCP to be the virtualization platform 26
OpenStack and XCP OpenStack supports XCP through XenAPI XenAPI: Management API exposed by XCP OpenStack compute interacts with the XCP hypervisor (XEN) 27
OpenStack Limitations (Cactus) Nova codebase = merger of Rackspace &NASA Cloud controllers Still Maturing Swift code base is mature and Ready for primetime HA, fault tolerance support in Cactus Release is in proposal stage Lack of good documentation on Setup/usage Diablo Release will be recommended for wide adoption 28
Conclusions OpenStack is becoming a default open source cloud fabric in IaaS space Ecosystem is an excellent opportunity to contribute to this exciting effort Wide adoption by Industry heavyweights guarantees major traction Lots of room for improvement but fast release cycles ensure quick fixes 29
